Unless the Queen were based in Balmoral, it would seem rather a long journey for a 90 year old monarch to have to make, especially given that she is scaling down her public engagements and delegating more to William and Harry with their military careers.

It would have been more prudent for the soldiers on recovery to have visited Buckingham Palace and received their medals there.

There is no real specific treatment for tonsillitis, which is mainly dealt with by paracetamol and fluids. Very unlikely to require hospitalisation unless for surgery. I wonder if Soldier 3 actually had some other ailment requiring the wire brush? - in which case he is deliberately misleading our Majesty, as well as being rude and disrespectful in front of her. In which case it is perfectly proper that she didn't give him a medal - court martial would be far more appropriate!

It might have been in the next ward, which was dealing with actual combat injuries, where one soldier informed the Queen that he had been shot up the backside.
"Rectum?" asked the Queen.
"No, just missed 'em" came the reply.
